First, as envisioned in the MSCA application, I worked on designing the CRS law dataset. For that I relied on the the OECD peer review reports which provide detailed information on how countries enforce the Common Reporting Standard (CRS). The 2020 report assessed whether domestic legal frameworks were aligned with OECD standards, focusing on the inclusion of financial assets and institutions. A second report in 2022 evaluated the effectiveness of CRS implementation in practice, examining factors such as communication with financial institutions, verification of reporting quality, penalties for non-compliance, and staffing. I created a dictionary to classify countries into low versus high enforcement along several dimensions. I describe this in the working paper section 3.1.2 Data on CRS Activation and CRS Enforcement and appendix A.1 The OECD Global Forum and the Common Reporting Standard, see

Once, the paper using this dataset is published (see the paper described below, we are currently on a revise and resubmit to a top filed journal), I will make the data publicly available on my website so that other researchers can use it for further projects.
Second, as envisioned in the MSCA application, I worked together with my co-authors on performing a granular comparison of the different AEOI systems locally implemented. The results of the analysis are provided in the working paper "Lost in information: national implementation of global tax agreements, co-authored with A. Alstadsæter, J. Miethe, & B. Stage. This paper studies how national implementation shapes individual responses to global agreements by looking at the introduction of the multilateral standard for automatic information exchange on financial assets, i.e. the Common Reporting Standard (CRS). We utilize rich micro-level data on all bank transfers to Norway. This provides us with unparalleled detail on hidden ownership structures. These data show a significant increase in cash repatriation from tax havens post-CRS implementation. Yet, we document substantial heterogeneity in responses down to a null result if CRS enforcement is weak. Relying on macroeconomic data on crossborder bank deposits, we employ model averaging techniques to establish the most important characteristics of the receiving countries that make the CRS more effective. Our results suggest that a highly digitized tax administration triggers twice the drop in tax haven deposits compared to a tax administration relying on paper tax returns. These results have implications for global policy initiatives more broadly. The working paper is available here
https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4630849(si apre in una nuova finestra). It is currently under revise and resubmission at the Journal of Public Economics which is a top field journal for public economics (ABS level 3, 8.8 CiteScore. 3.4 Impact Factor): together with my co-authors, we are working on the revision and plan to submit it back to the Journal by the end of the year. If successful, the paper might be accepted to publication in 2026.
